Biometry is a technique that analyses physical and behavioural traits to authenticate a person's identity. Biological, morphological, and behavioural biometrics are examples of different forms of biometrics. Fingerprint, facial recognition, voice recognition, iris recognition, and signature recognition are the most prevalent biometric IDs used today. Next-generation biometrics offer high levels of protection and assurance, as well as being convenient and quick to use, non-transferable, and difficult to forge. The global next-generation biometric market is being influenced by rising demand for security applications such as national ID cards, border crossing, and government benefits, among others. As a result, throughout the projected period, the worldwide next-generation market is expected to reach US$ 71.91 billion.
